Localization of text messages during main() function

[Robert Hairgrove]

Sometimes errors will occur before the main window is shown, or possibly warnings which can be shown just after calling QMainWindow::show(). However, I have not yet been able to show localized error messages except within the body of a function belonging to a descendent of QObject. I can translate them im QtLinguist, but only the original language is shown.

Is there a well-known workaround for this? I suppose I could make them member variables in my main window class and defer showing the messages until after the main window opens, but maybe there is another way?

@Robert-Hairgrove
Assuming what you say about QObject is correct (I don't know), you don't have to wait for the declaration/creation/showing of QMainWindow to use that. For example, you might put up a QDialog before/without even having a QMainWindow. So that cannot be the issue,

@Robert-Hairgrove you can install a QTranslator and set the desired language even in main.cpp see this example...

#include <QApplication>
#include <QPushButton>
#include <QTranslator>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QTranslator translator;
    translator.load("hellotr_la");
    app.installTranslator(&translator);

    QPushButton hello(QPushButton::tr("Hello world!"));
    hello.resize(100, 30);
    hello.show();

    return app.exec();
}

Thanks ... the problem was that my translations were being updated to a different location. Now it is working!
